Peak Calling with 'MOSAiCS'
R package 'mosaics' implements MOSAiCS, a statistical framework for the analysis of ChIP-seq data,
proposed in
Kuan PF, Chung D, Pan G, Thomson JA, Stewart R, and Keles S (2010).
“A Statistical Framework for the Analysis of ChIP-Seq Data.” (Submitted)
MOSAiCS stands for “MOdel-based one and two Sample Analysis and Inference for ChIP-Seq Data”.
Based on careful investigation of biases in ChIP-seq data such as mappability and GC content,
MOSAiCS has been developed as a fexible mixture modeling approach for detecting
peaks of one-sample (ChIP sample) or two-sample (ChIP sample and matched control sample) ChIP-seq data.
